RAILROAD-TIE.

sPEcIEIcATIoN forming part of Letters :Patent No. 725,75eiatea April 21, 1903.

Application led September 10,1902. Serial No. 122,874. (No model.)

To @ZZ whom, it III/ty concern,.-

Be it known that I, EDWARDAMCCO'NNELL, of Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Railroad-Ties; and I hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in railroad-ties; and its object is to produce a very simple, cheap, and easily-constructed metallic tie which can be rolled in bar form and cut to the desired length, Will present sufficient bearing-snrface to afford ample support for the rails against vertical pressure, will also present sufficient vertical surface to prevent lateral movements of the tie, and the vertical surfaces may be roughened or corrugated, if desired, to increase the resistance to longitudinal movement, which can be easily tamped With the ballast, and to which the rails may be secured by simple but secure fastenings.

To these ends the invention consists in the novel construction of the tie illustrated in the accompanying drawings and hereinafter described and claimed.

Figure lis a transverse section of a rail- Way, showing a side elevation of the tie. Fig. 2 is an elevation of the opposite side of tie. Fig. 3 is a top View thereof. Fig. 4 is a detail sectional view on line 4 4, Fig. 3. Fig. 5 is an end View, and Fig. 6 is a View of a tie with a corrugated vertical flange.

The tie is composed of a length of L angleiron which is arranged with one iange, A, horizontal andthe other, B, vertical. Preferably the horizontal top flange A is Wider than the vertical flange B; but Ido not restrict myself to such particular relative di- Inensions. The vertical flange B may be plain or roughened or corrugated, as indicated at b in Fig. 6, to prevent endwise movement of the tie when in position in the ballast. side opposite flange B, is a shallow upstanding ange C, which is provided at points separated the distance apart of the rails with notches c, in which the base-flanges t of the rails T are confined, the bases of the rails On the top horizontal iiange A, at the` resting upon the top iiange A of the tie. The notches c assist in maintaining the rails the proper distance apart.

The rails are clamped Yto the tie by means of clips D, which are provided with a dovetail lateral groove d2, in Ywhich is inserted a plate c, filling said groove `and flush with the face of clip, `one end of said plate extending beyond the edge of clip. As shown, the horizontal flange A of the tie is provided with elliptical openings on opposite sides of the rails for the reception of the elliptical shoulder e Aof the bolt to prevent the latter from turning when passed through the perforations made in the flange A and through the clips, and the whole secured by nuts CZ.Y When nut is screwed down on theplate e,the projecting end thereofis bent up against the side of nut,thereby preventing it from turning,rthe Whole thus affording a secure and simple means for fastoning-the rails to the ties. I prefer the use of detachable fastenings D rather than to have either of them made integral with the tie, as I consider thev construction shown less expensive. I do not, however, restrict myself to the use of the specific fastenings shown.

It will be observed that my tie can be slipped in and out of place as readily as a Wooden tie, that the flange A has all the bearing-surface upon the ballast or earth that a wooden tie would have, so that the rails will be amply supported, and the flange B has all the'lateral bearing-surface in the ballast that an ordinary Wooden tieV of the same height would have. Moreover, the ballast can be readily taniped under the ange A from 'the side opposite flange B, which is a great advantage in the construction of my tie over the ordinary forms of metal ties, rWhich are generally U -shaped or hollow in cross-section,

so that it is practically impossible in many' of them to tamp the ballast properly under the tie.

My ties can be rolled in lengths froln metal bars in an ordinary rolling-mill by using suitably-grooved rolls, and as the entire tie is integral and lhas no compound parts it can be very cheaply manufactured, and while eX- ceedingly simple is, I believe, entirely novel and superior to any ties heretofore manufactured or patented.

IOO

Having thns described my invention, what I therefore claim as new, and desire to seen re by Letters Patent thereon, is-

l. The herein-described metallic railwaytie formed ot' angle-iron having a horizontal rop Hange to which the rails are attached, a depending vertical iiange at one edge of the top iange, and a shallow upstanding flange on the top fiange at the edge opposite the vertical fiange, said shallow ange being notched to accommodate the rails and provided with means substantially as described for securing the rails therein.

2. The combination ofthe metallic railroadtie L-shaped in cross-section having a single depending iiange corrugated, and a shallow vertical flange at the edge of its horizontal ange opposite the depending ange, the shallow flange being notched; with therails extending transversely of the tie and engaging the notches in the shallow flange, and means
